. SPECIFICATION forming part of Letters I Application filed May 10,1883. (Model) To all whom, it. may concern.-

'Be it known that we, SoLon R. RUsr and ARTHUR E. RUST, of Pine Meadow, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a description, reference being had to the ac companying drawings, where- Figure 1 is a view in longitudinal vertical section of a plane embodying our improvements on plane denoted by line x of Fig. 2. Fig. 2 is a top view'of the same. Fig. 3 is a detail view in cross-section on the line y y of Fig. 1. Fig. 4 is a detail end view'of the carriage, looking from below.

Our invention has for its object the construction of planes cheaper and more readily adjusted to varied uses than the forms now in common use, and it consists in the special arrangement and combination of the parts for adjusting the cutting-iron and clamping the same, and in changing-the character of the plane from a single to a double iron, as'hereinafter more particularly described.

In the accompanying drawings, the letter a denotes a"body of common form, and made of any desirable material, as iron; I), the usual mortise or opening through to the face of the plane; a, the cutting-bed; d, atransverse flange provided with the socket d,- e, a carriage having upon the lower side a tubular proj ection adapted to fit into and move longitudi nally in the socket d, and on its upper side the arms f, provided with the interiorly-pro- 3 jecting flanges or their equivalents.

On the carriage, and between the arms, rests the cutting-iron g, which is a flat piece of metal provided with a chisel-edge, and upon it, and also adapted to slide between the arms, is arranged the cap-iron and clamp h, which has upon each side the projections h, which limit the forward movement of the clamp, and at its rear end, in a threaded socket, the clamp-screw h. Y

The screw-spindle t is rotarilysecured in the tubular projection on the carriage, as by means of the transverse pin j, and its lower end projects into and operates in the nut formed in the body of the plane. This peculiar arrangement of the carriage enables it to have a rocking motion sidewise, or transversely of the plane, and at the same time makes it Patent No. 287,584. dated Qctober 30, 1883.

1 adjustable in the plane of the cutting-iron. This rocking motion of the carriage enables one to adjust the back of the plane-iron to a perfect bearing on the cutting-bed, and at the same time support and hold it against longitudinal motion.

The cap-iron is made to serve as a clamp by its lower edge, resting upon the cutting-iron near its lower end, passing under the flanges on the arms, which serve as fulcrums, and by being raised from the cutting-iron near the upper end by means of the clampscrew, the lower end of which takes against the face of the iron. It serves the purposeof the ordinary cap-iron, when desired, and at the same plane in the form'known as (single-iron planes.

One peculiar invention consists of the combination of cap ironand clamp, so arranged that the relative positions of the cutting-edge of the iron and the front edge of the clamp are not'changed when the iron is adjustedto fix thethickness ting-iron and the cap-iron, and possesses the further advantage of simplicity and ready adjustment to various uses.

The thickness of the shaving made by the plane is adjusted by means of the screw-spindle, which has asuitable head for operating with the thumb and finger. In order to enable the tubular projection to slide readily, or to rock in the socket d, we slab off, as seen in Fig. 3, portions of its upper surface, to decrease the bearing-surface within the socket. This, however, is not essential to the perfect operation of our device, as. the carriage may have a downward projecbody, or be adapted to rock in many ways obvious to the skilled mechanic on slight inspection-of our device.
